Hi everyone, I am having issues with CPU usage in Logic Pro X. My setup is as written in my signature below. If I record arm a track, insert a guitar amp sim (Amplitube 3, podfarm or Logic's Amp Designer) and then start playing, within 10 seconds the CPU will peak with corresponding glitchy audio. I have the buffer set to 64 samples, but it makes only minimal difference if I increase this - the average load on the CPU seems to decrease (as observed in Logic's CPU meter) but I still get the CPU maxing out periodically. I'm not even recording - just trying to play the guitar on a single audio track with a single plug-in in a project with no other tracks in it. It seems crazy that I can't even do that without the CPU maxing out. I thought it may be the Scarlett 2i2 drivers but they were fine with Logic Pro 9 and the Mountain Lion OS so it seems weird that they would be the problem. Regardless, I will contact Focusrite to see if they have a new driver to be released soon. Anyone else having simliar issues? Cheers, Jeremy

Thanks for your reply David, Good to know it's not just me. Hopefully it will be fixed soon. Cheers, Jeremy

Hi everyone, In Logic Pro X auto input monitoring isn't working for me. In order to hear what I am playing I have to have the input monitoring button selected on the track. I have software monitoring selected in the preferences so that isn't the problem. I have experienced this on two macs. I think it's highly likely that I'm doing something wrong but is anyone else having this problem? Cheers, Jeremy

Hi Eric, Yep I'm missing both of those...the weird thing for me tho is that Logic said it was scanning 22 audio units but only 21 show in the Audio Units Manager. Anyway, thanks for your help.

Thanks for your responses I've updated my signature...David I'm on OSX 10.6.8

Ok thanks guys...so the AUsampler should show up in my Audio Units manager then? It was the only one on the support page screenshot I found that wasn't in my list... It just seemed odd that logic told me it was scanning more audio units than what actually showed up (ie it said 22 were scanned but there are only 21)

Hi everyone, I just did a clean install of Logic Pro 9 on an iMac and I noticed when starting Logic for the first time that when it scanned for the AU plugins it scanned for 22 but there are only 21 listed in the Audio Units Manager. And I'm sure when I've previously installed Logic pro it has said it's scanning 23 AU plugins. I wonder if I'm missing some plugins? Can anyone please provide me a list of all stock AU logic plugins? I found a logic support article which has a screen shot of the Audio Units manager and the only Logic plugin I seem to be missing from that list is AUSampler - is that a stock plugin? Cheers, Jeremy

Ok, I've 'found' one good tone (actually stolen from The Police as reported by Stewart Copeland in an interview I stumbled across): Record one guitar thru the JC-120 (with the chorus) and miced with one mic on each speaker, panned hard left and right. Then play another take thru the same amp, but this time reverse the panning of the mics. Doing two takes like this and then reversing the panning means you end up with an unaffected and a chorused signal both left and right. I just did a mock-up of it in Amplitube and it sounds very rich. Of course it might be too '80s' for some, but I'm digging it Thanks for your suggestions Chimpotle, much appreciated. Time to go celebrate New Years now! Cheers, Jeremy.

Hi Chimpotle, Yeah it really is the stereo chorus that 'makes the sound' of the JC-120 for me so I'd definitely be aiming to capture that. So in your post above are you suggesting just a single guitar played through the JC-120 (not double-tracked) but miced in stereo? I do have access to a vintage Fender twin as well - that definitely is a nice amp so I might have more of a play around with that as an alternative. Since making the first post, I have come to the conclusion that using the same amp left and right and just changing things slightly (such as using different mics or moving mics slightly as you suggest) will produce a better sound than having two different amps left and right. Cheers Jeremy.

Hi Chimpotle, Thanks for the reply. I have access to a good selection of amps as well as modelers, so I can use either. In my experimenting with different tones, I've found that I am LOVING the sound of the Roland JC-120 for the main parts in these tracks. Overall I think the JC-120 is a bit 'sterile' for my tastes...but...once you kick in the stereo chorus I just love the sound. I think it could be hard to find another tone to compliment the JC-120 tho because it's just sooo clean. But I think I need to do some experimenting as you say. Does anyone else have any tried and true methods that they could share? Cheers, Jeremy.

Hi there, I'm recording some mellow, half-time rock songs, all based around clean picked guitar. The songs are very stripped back so I'm thinking I want to double-track the main parts and then pan them left and right. My main question is this: If I've got a clean guitar panned left and a clean guitar panned right playing EXACTLY the same part is it best if they have the exact same sound (same guitar into same amp + same effects), or should I vary the tone between the two guitars? It seems like it might be best to vary the tone, but then I think if I start changing effects chains between the two guitars or using a different amp etc that one of the guitars may end up sounding more dominant and therefore make the mix sound unbalanced. Any input is much appreciated. Cheers, Jeremy.

Hi triplets, Thanks for posting that link - that makes for some interesting reading. Maybe I'll just look at getting a Duet instead. Cheers, Jeremy.

Thanks for the reply. I live in New Zealand - those two interfaces are the same price here. I emailed Focusrite and Presonus - Presonus have yet to get back to me, but Focusrite have said that they don't support daisy-chaining. Doesn't mean it won't work of course but maybe it's a gamble...I'm also considering an Apogee Duet which is much more expensive but maybe worth it... Cheers, Jeremy.

Hi, I am looking for an interface to use with my just-ordered 13" MacBook Pro. On the maybe list at the moment are the Presonus FireStudio Mobile and the Focusrite Saffire Pro 14. I would be using a Lacie D2 Quadra hard drive connected direct to the computer, and the interface would need to be connected to the hard drive. I.e. MacBook Pro -> Lacie D2 Quadra connected via f/w 800 -> Interface connected to Lacie via f/w 400. If anyone could please tell me if they are successfully using this set-up with one of these interfaces (or something similar) I would really appreciate it. Cheers, Jeremy.

Haha, that's a good point David! My budget is real tight at the moment so my options are: 1) the base MacBook Pro (2.4 GHz core 2 duo) 2) the base iMac (3.06 GHz i3) The only thing the MBP has going for it is the portability (which is important to me, but I guess I could live without). The iMac on the other hand would appear to be a much better computer: - faster processor, which also supports hyperthreading - larger, faster hard drive - larger screen, higher resolution - more usb ports I would assume I would see much better performance (cpu-wise) from the iMac, correct? I don't do huge sessions, but do use plugs like Superior Drummer and Amplitube 3 on every session so I can see the 2.4 GHz MBP struggling a bit... Cheers, Jeremy.
